GREEN BUILDING GUIDE Romilly Madew, Chief Executive Green Building Council of Australia As you walk through a city – be it Hanoi, Houston or Hobart – it’s easy to fall into the trap of thinking our urban environments to be invulnerable. Beautiful buildings and impressive infrastructure rise and evolve around us, and for most, cities are a representation of hope, possibility and opportunity. It’s our default to think of urban areas as living, breathing, self-sustaining organisms unto themselves, and in many ways they are. But as anyone who has fallen victim to one of Australia’s all too frequent extreme weather events will attest, our cities are delicate systems. And factors that can upset their fragile balance are just around the corner. Sydney’s recent storms, Brisbane’s series of floods, or Victoria’s almost yearly heatwaves and bushfires are the kinds of events that throw our cities’ vulnerabilities into the sharpest relief. Yet failure to address the social and economic challenges facing them poses an equal threat to their long-term sustainability. To build truly strong, sustainable and resilient cities, the first step is remembering that a chain is only as strong as its weakest link. Cities are a matrix of economic, social and environmental components, and resilience can only be achieved when investment is made across all of these areas. The City of Melbourne’s Resilient Melbourne Strategy, which has been developed following the city’s induction into the Rockefeller Foundations 100 Resilient Cities program, has adopted this new, integrated way of thinking about urban resilience. Its strength lies in an acknowledgement that social and economic problems work to intensify the destructive impacts of environmental problems, and vice versa. For example, the strategy says that while Melbourne is “liveable for those with easy access to essential services and a well-paying job, living in the world’s sixth-most expensive city presents major difficulties for many Melburnians, particularly in areas of entrenched disadvantage and those located furthest from the central business district.” It recognises that unaffordable housing is a precursor to urban sprawl, which in turn gives way to congestion – a problem that Infrastructure Australia says will cost GOVLINK » ISSUE 3 2016 11
